MICROSPEAKER HAVING 3 MAGNET

摘要

The present invention provides a microspeaker having three magnets for preventing the separation of a side magnet. The present invention includes: a frame; a yoke which is combined with the frame and forms a lower side; a center magnet which is fixed on the yoke; a pair of side magnets which is fixed on the yoke and positioned on both sides of the center magnet; a center top plate which is attached to the upper side of the center magnet; a side top plate which is attached to the upper side of the side magnet; a voice coil having a lower side which is located in an interval unit between the center magnet and the side magnet and an interval unit between the center magnet and a bending unit and vibrates by mutual electromagnetic force; and a vibration plate which vibrates by the voice coil. The yoke equips the bending unit to be bent to the upper side so as to have regular intervals with the end of the center magnet on a side where the side magnet is not located. The width of the bending unit is the same as an interval between the pair of side magnets.
